1-4 General Information MN1942
Do not connect AC power to the drive terminals U, V and W. Connecting AC power to these
terminals may result in damage to the drive.
Baldor does not recommend using “Grounded Leg Delta” transformer power leads that may
create earth/ground loops and degrade system performance. Instead, we recommend using
a four wire Wye.
Drives are intended to be connected to a permanent main power source, not a portable
power source. Suitable fusing and circuit protection devices are required.
The safe integration of the drive into a machine system is the responsibility of the machine
designer. Be sure to comply with the local safety requirements at the place where the
machine is to be used. In Europe these are the Machinery Directive, the ElectroMagnetic
Compatibility Directive and the Low Voltage Directive. In the United States this is the National
Electrical code and local codes.
Drives must be installed inside an electrical cabinet that provides environmental control and
protection. Installation information for the drive is provided in this manual. Motors and
controlling devices that connect to the drive should have specifications compatible to the
drive.
Failure to meet cooling air flow requirements will result in reduced product lifetime and/or
drive overtemperature trips.
Violent jamming (stopping) of the motor during operation may damage the motor and drive.
Operating the MicroFlex
e
100 in Torque mode with no load attached to the motor can cause
the motor to accelerate rapidly to excessive speed.
Do not tin (solder) exposed wires. Solder contracts over time and may cause loose
connections. Use crimp connections where possible.
Electrical components can be damaged by static electricity. Use ESD (electrostatic
discharge) procedures when handling this drive.
If the drive is subjected to high potential (‘hipot’) testing, only DC voltages may be applied.
AC voltage hipot tests could damage the drive. For further information please contact your
local Baldor representative.
Ensure that encoder wires are properly connected. Incorrect installation may result in
improper movement.
The threaded holes in the top and bottom of the case are for cable clamps. The holes are
11.5 mm deep and accept M4 screws, which must be screwed in to a depth of at least 8 mm.
Removing the cover will invalidate UL certification.
